Clean Water, Low Maintenance


PowerFlo™ Filtration, Pressure Side System

Reliable and virtually self-maintaining, PowerFlo™ filtration most effectively utilizes power from the jet pump to clean and sanitize every drop of your spa water.

While others pull dirty water over open, visible filters on the pump suction side, through the pump and back into your spa, the PDC PowerFlo™ design positions the filter on the push side of the pump to efficiently maximize pump power for cleaner water.

Used water and surface debris is captured through waterline and bottom safety suctions and sent to the pump, where the power of the jet pump forcefully pushes the dirty water through a deep pleated filter cartridge, capturing all dirt and contaminants. The filter is concealed within the spa shell, hidden from view so all you see is polished crystal clean water returned to your swim spa or hot tub; no muss, no fuss. Standard on Luxury, Premium Series and TruSwim® swim spas. Learn more here

Pristine™ Filtration, Suction Side System

The Pristine™ filtration system uses the suction-side of the jet pump to pull water through the filter for a deep cleaning. The deep pleats in the filter cartridge capture debris, dirt and contaminants, returning water polished and clean for your enjoyment. Reliable and virtually self-maintaining, Pristine™ filtration effectively and efficiently assures water is clean and sanitized for relaxation anytime you choose. Standard on LifeStyle Series,  Splash Series, Vitality and Synergy swim spas.
